BCRAGD hosts seminar this morning

By David Mauk General Manager, BCRAGD

The Bandera County River Authority and Groundwater District is hosting a water conservation event this morning, Thursday, Sept. 26 from 10 am to noon at their offices at 440 FM 3240 in Bandera. The mini-seminar will cover the current drought and efficient uses and conservation of our limited water resources. The event is free and open to the public.
The reality of the situation is that we live in an area that experiences feast or famine conditions in regards to our rainfall. It seems that our county now is in a period of extended drought broken up with intermittent floods. Unfortunately, the flood has been slow in arriving during this current drought.
Most people residing in Bandera County rely on well water for their household and ranching needs. Our aquifers in Bandera County have very slow recharge from rainfall and become stressed during these times of drought. Most people understand this and practice conservation. However, livestock, wildlife, and gardens may not necessarily survive through drought conditions without supplemental watering from the water wells.
One management tool that is increasingly being utilized to provide supplemental water is rainwater harvesting. Rainwater harvesting can be implemented to supplement groundwater usage. Basically, rainwater is captured from a roof during rainfall events and stored in tanks or cisterns. The captured water then can be utilized when needed during periods of little or no rainfall.
Rainwater harvesting has one primary limitation that needs to be addressed before designing and implementing a system. Obviously, it is rainfall dependent. This limitation can be offset with increased roof area to capture the rainfall and increased storage capacity. When rains finally do come, the system must have enough storage capacity to capture the rainfall.
The Bandera County River Authority and Groundwater District (BCRAGD) has rainwater harvesting manuals and literature for the general public. Every landowner and rancher should at least explore the possibility of utilizing rainwater harvesting to augment their water usage and conserve their groundwater resources.
